Date: Sat, 24 Oct 2015 20:09:53 +0000
Subject: [PATCH 47/47] libgcc_s: Use alias for __cpu_indicator_init instead of
symver
Adapter from
https://gcc.gnu.org/ml/gcc-patches/2015-05/msg00899.html
This fix was debated but hasnt been applied gcc upstream since
they expect musl to support '@' in symbol versioning which is
a sun/gnu versioning extention. This patch however avoids the
need for the '@' symbols at all
libgcc/Changelog:
2015-05-11 Szabolcs Nagy <szabolcs.nagy@arm.com>
* config/i386/cpuinfo.c (__cpu_indicator_init_local): Add.
(__cpu_indicator_init@GCC_4.8.0, __cpu_model@GCC_4.8.0): Remove.
* config/i386/t-linux (HOST_LIBGCC2_CFLAGS): Remove -DUSE_ELF_SYMVER.
gcc/Changelog:
2015-05-11 Szabolcs Nagy <szabolcs.nagy@arm.com>
* config/i386/i386.c (ix86_expand_builtin): Make __builtin_cpu_init
call __cpu_indicator_init_local instead of __cpu_indicator_init.
